heh, a shock does not raise or lower suspension. all they do is recover from jounce (going over bumps and stuff).
they are not cheapest or easiet to lift, a SFA is...but they are realitivly cheap. allignment woes are mostly toe because they put more load on the camber and caster. camber can be fixed with allignment bushings but caster is still outta wack.
go for it and make sure u get a proper allignment after.
